Description

Cutting device

The present invention relates to a die cutting device used for forming a workpiece cutting piece of a certain shape from a sheet-like workpiece by die cutting.

This case claims priority based on Japanese Patent Application No. 2014-190793 filed in Japan on September 19, 2014, and its content is incorporated herein.

As one of the methods of forming a workpiece cutting piece having a certain shape from a sheet-like workpiece, a method of performing die cutting using a cutting die is known.

As a cutting die used for die cutting using a thin-walled film as a sheet-like workpiece, for example, a cutting die having the following structure has been proposed: a region inside and outside the cutter in the surface of the base plate An elastic material such as a sponge or urethane or a rubber plate having a height that can hide the tip of the cutter is provided. In addition, when using this cutting die, a technique has been proposed in which a sheet-shaped workpiece is placed on the upper side of the elastic material, and a blade tip is placed on the upper side of the sheet-shaped workpiece to abut the cutting edge of the cutter. After the interposer is formed in this state, it is pressed by a pressing roller (for example, refer to Patent Document 1).

However, in recent years, as one of manufacturing methods of a product having a three-dimensional shape made of a fiber-reinforced resin such as CFRP or GFRP, the following methods have been developed: by die cutting using a cutting die, The sheet-like workpieces made of resin-impregnated fibers are used to form workpiece cutting pieces with slightly different shapes, and these workpiece cutting pieces are laminated into a plurality of layers in a predetermined order and arrangement, and then integrated to form The desired three-dimensional shape.

In such a manufacturing method, since the error (shape) of the shape (outer shape) of the workpiece cutting piece formed by die cutting affects the three-dimensional shape finally formed, in the die cutting of the workpiece cutting piece by cutting, Asked for accuracy.

However, as shown in Patent Document 1, when the sheet-shaped workpiece is cut, even if the sheet-shaped workpiece is pressed by a pressing roller through an interposer, it is not compressed to the elasticity of being disposed inside and outside the cutter. When the material is at a height below the position of the tip of the cutter, the sheet-shaped workpiece will not contact the cutter. Therefore, when the sheet-like workpiece is cut, the sheet-like workpiece does not easily enter the inside of the cutter, and the position of the sheet-like workpiece with respect to the cutter is liable to occur.

FIG. 3 is a schematic view showing a sheet-like workpiece pressed during cutting, FIG. 4 is a schematic view showing a pin provided on a cutting die body, and FIG. 5 is a schematic view explaining a height dimension of an elastic member inside the blade.

The cutting die device of the present invention is shown at the first FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 2 are formed by a cutting die body 2 and a cover 3 arranged above the cutting die body 2.

The cutting die body 2 includes: a base plate 4; a cutter 5 provided on the base plate 4 and protruding from the surface thereof; a blade outer elastic member 6 provided on an outer side region of the cutter 5 in the surface of the base plate 4; and a blade The inner elastic member 7 is provided on an inner region of the cutter 5 in the surface of the base plate 4.

The cutter 5 is continuously formed into a ring shape along the outer shape (contour) of the work cutting piece X to be formed. In addition, the cutting blade 5 has its blade tip 5a protruding from the surface of the base plate 4 with a size larger than the thickness dimension of the sheet-like workpiece W.

In addition, the form of the cutter 5 may be any one of a conventional Thomson blade, a carving knife, and an etching knife, and a Thomson knife, a carving knife, and an etching may be combined in each part. Two or three of the knives.

As shown in FIG. 2, in the present embodiment, four cutters 5 having a substantially parallelogram shape are provided on the surface of the base plate 4.

Here, as shown in FIG. 1A, FIG. 1B, and FIG. 1C, the die cutting device 1 of the present invention is used in the pressing when die cutting from a sheet-like workpiece W described later to form a workpiece cutting piece X. The illustrated roller press is used as the pressing mechanism. In addition, the die cutting device 1 of the present invention is a pressing roller of the roller press, as shown by an arrow D in FIG. 2, while moving relatively in a direction along the long side of the rectangular base plate 4, The pressing roller is used for pressing. Therefore, the cutting die device 1 of the present invention is The region where the pressing roller receives the pressing load is a linear region extending along the axial center direction of the pressing roller, that is, a linear region extending in a direction perpendicular to the arrow D direction. Therefore, the die-cutting device 1 of the present invention is moved relative to the pressing roller in the direction of arrow D, so that a region receiving a linear pressing load in a direction perpendicular to the direction of the arrow D is directed toward the arrow. The D direction moves in the opposite direction. Thereby, the cutting device 1 of the present invention is sequentially pressed toward the direction along the long side of the rectangular base plate 4 to perform pressing across the entire surface.

Here, as described above, when the die cutting device 1 of the present invention is pressed by the pressing roller, an area that receives a linear pressing load in a direction perpendicular to the direction of the arrow D is oriented toward the arrow. The D direction moves in the opposite direction. Therefore, for example, when a continuous portion of the cutter 5 is disposed along a direction perpendicular to the direction of the arrow D, concentration of resistance to a pressing load may occur at that portion. Therefore, the arrangement (nesting) of the four cutters 5 in the surface of the base plate 4 is preferably set such that a portion of each cutter 5 that has a linearly extending shape is disposed away from the arrow D The direction of a right angle. In the present invention, in order to disperse the resistance to the aforementioned pressing load among the portions where the cutters 5 are disposed, the portions of each cutter 5 that are linearly extended are disposed at right angles to the direction other than the direction of the arrow D. Direction. Thereby, in the die cutting device 1 of the present invention, it is possible to suppress the sudden application of a large force when pressing with the pressing roller, so that the transportation in the roller press can be stabilized.

In addition, beyond the cutters 5 on the surface of the base plate 4 The side region is provided with, for example, the arrangement shown in FIG. 2, and the remaining sheet cutting blade 8 is used to die-cut the workpiece cutting sheet X from the sheet-shaped workpiece W. The remaining remaining sheet Y is cut into a size that is easy to handle. The remaining blade cutting edge 8 is set to the same height as the cutting blade 5 from the surface of the base plate 4 to the cutting edge.

In addition, as shown in FIG. 2, the remaining piece cutting blade 8 is set to extend in a direction offset from a right angle direction of the arrow D by a certain angle. When a plurality of remaining sheet cutting blades 8 are provided, each of the remaining sheet cutting blades 8 is arranged in a direction of an arrow D staggered from each other. The reason why the remaining piece cutting blades 8 are formed as described above is because, similarly to the arrangement of the respective cutting blades 5 described above, in order to arrange a portion where a continuous portion of the remaining piece cutting blades 8 is arranged, or a plurality of pieces are arranged. Each of the remaining pieces cuts the blade 8 so that the resistance to the pressing load is dispersed. Therefore, even with such an arrangement of the remaining sheet cutting blades 8, in the die-cutting device 1 of the present invention, it is possible to suppress the sudden application of a large force when pressing with the aforementioned pressing roller, so that it is possible to Stabilize the transportation in the aforementioned roller press.

A blade outer elastic member 6 having a certain height dimension is provided in a region outside the respective cutting blades 5 on the surface of the base plate 4 and does not interfere with the remaining blade cutting edge 8. The blade outer elastic member 6 is formed of a material such as sponge, urethane, or rubber, and can be elastically deformed by being compressed in the vertical direction.

In addition, in this specification, the term "height" simply refers to the amount protruding from the surface of the base plate 4, and does not include the directionality of the vertical direction.

The height dimension of the outer elastic member 6 of the blade is set The size is the same as or larger than the protruding height of each cutting blade 5 from the surface of the base plate 4 to the cutting edge 5a.

The inner area of each of the cutters 5 in the surface of the base plate 4 is provided with an inner side of the blade having a height dimension lower than the protruding height of the cutter 5 from the surface of the base plate 4 to the tip 5 a of the cutter 5. Elastic member 7. Thereby, the height difference between the edge 5a of the cutting blade 5 and the surface of the elastic member 7 inside the blade is formed inside the cutting edge 5a of the cutting blade 5.

The blade inner elastic member 7 is made of a material such as sponge, urethane, or rubber, and can be elastically deformed in the same direction as the blade outer elastic member 6 in a vertical direction. In addition, the material of the blade inner elastic member 7 may be the same material as the material of the blade outer elastic member 6 or any of different materials.

As shown in FIG. 5, the height dimension p of the elastic member 7 on the inner side of the blade is preferably set to the thickness of the sheet-like workpiece W by setting the protruding height of each cutter 5 from the surface of the base plate 4 to the tip 5a as q. The size is set to r, and when the sheet-like workpiece W to be described later is cut by each cutter 5, the amount that the cutting edge 5 a of each cutter 5 penetrates into the cover 3 is set to s, and is set to the following number The value calculated by the formula.

p = q- (s + r)

According to this setting, it is possible to prevent deformation of the elastic member 7 inside the blade when cutting the sheet-like workpiece W, so that when cutting the sheet-like workpiece W and forming the workpiece cutting piece X, the sheet-like workpiece W can be prevented from accompanying the blade inside There is a possibility that the elastic member 7 is deformed in a vertical direction and its position is shifted.

Furthermore, as shown in FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 2, the area where the sheet-like workpiece W is placed on the upper surface of the blade outer elastic member 6 and the blade inner elastic member 7 For example, a fluororesin sheet 9 made of tetrafluoroethylene or other fluororesin is integrally provided on the surface as a sheet having a material having higher tensile rigidity than each material and a smaller friction coefficient than each material. In the die-cutting device 1 of the present invention, as described above, when pressing with the pressing roller, a region that receives a linear pressing load in a direction perpendicular to the direction of the arrow D is directed toward the direction of the arrow D. The opposite direction moves in order. Therefore, the blade outer elastic member 6 and the blade inner elastic member 7 simultaneously deform the linear portion of the blade that bears the pressing load from above along a direction perpendicular to the direction of the arrow D in a partially concave manner, and The recessed portion is moved in a direction opposite to the direction of the arrow D. At this time, since the fluororesin sheet 9 with higher tensile rigidity is integrally provided on the upper surfaces of the blade outer elastic member 6 and the blade inner elastic member 7, they are integrated with the blade outer elastic member 6 and the blade inner elastic member. 7 is a comparison with a single case, and the deformation that is partially depressed due to the pressing load can be averaged in the direction of the arrow D. Therefore, it is possible to suppress local deformation of the sheet-like workpiece W placed on the upper surface of the blade outer elastic member 6 and the upper surface of the blade inner elastic member 7. In addition, when the blade outer elastic member 6 and the blade inner elastic member 7 are deformed as described above, the fluororesin sheet 9 and the sheet-like workpiece W can slide to prevent wrinkles from occurring in the sheet-like workpiece W.

In addition, in the case of a configuration in which the fluororesin sheet 9 is integrally provided on the upper surface of the blade outer elastic member 6, it is only necessary that The height dimension of the blade outer elastic member 6 after adding the thickness dimension of the fluororesin sheet 9 is the same size as the protruding height of the cutting blade 5 from the surface of the base plate 4 to the cutting edge 5a of the cutting blade 5 or is larger than that. A larger size is sufficient.

Similarly, in the case where the fluororesin sheet 9 is integrally provided on the upper surface of the blade inner elastic member 7, the height dimension of the blade inner elastic member 7 after adding the thickness dimension of the fluororesin sheet 9 is added. It may be lower than the protruding height of the cutter 5 from the surface of the base plate 4 to the tip 5 a of the cutter 5. In this case, the preferred height dimension p of the blade inner elastic member 7 shown in FIG. 5 is as shown by the two-point chain line in FIG. 5 as long as it is set to include the thickness dimension of the fluororesin sheet 9 The height of the elastic member 7 inside the blade is sufficient.

In addition, as shown in FIG. 1A, FIG. 1B, and FIG. 1C, the surface of the base plate 4 has a plurality of parts on the outer elastic member 6 of the blade near the outer side of the area where the sheet workpiece W is placed, and faces A pin 10 is provided on the upper side to prevent the cover 3 from shifting.

On the other hand, as shown in FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 4, the cover body 3 is inserted in a position corresponding to the arrangement of the pins 10 of the cutting die body 2 in the vertical direction. There are pin insertion holes 11 for inserting each pin 10 from below.

As shown in FIG. 2, each pin 10 is preferably arranged in an arrangement along three of four sides of a rectangular sheet-like workpiece W. This is because when the sheet-like workpiece W is mounted on the upper side of the blade outer elastic member 6 of the die body 2, the sheet-like workpiece W can never be provided. The side of the pin 10 is arranged along the upper surface of the elastic member 6 on the outside of the blade, and it is easy to install the sheet-like workpiece W to the die body 2. In addition, the blade outer elastic member 6 is provided at a position corresponding to the arrangement of each pin 10 and is provided with a hole or a cutout for common use of the pin insertion.

The pins 10 on the base plate 4 and the pin insertion holes 11 on the cover 3 side corresponding to the pins 10 are arranged at a certain interval in the direction of the arrow D. This is in the die cutting device 1 of the present invention. As described above, when pressing with the pressing roller, the area receiving the linear pressing load in a direction perpendicular to the direction of the arrow D will face the aforementioned area. Arrow D moves in the opposite direction in order. Therefore, even if the lid body 3 is deformed so as to bend downward at a portion subjected to the pressing load, any one of the pin 10 and the pin insertion hole 11 arranged in the direction of the arrow D will be engaged, and the lid body 3 can be prevented. Of the offset.

Further, as shown in FIG. 4, the pin 10 is composed of a cylindrical pin shaft portion 12 extending upward and downward, and a conical ladder-shaped pin head portion 13 provided on the upper end side of the pin shaft portion 12. .

The pin portion 12 is a dimension obtained by adding the vertical dimension from the surface of the base plate 4 to the surface of the fluororesin sheet 9 on the elastic member 6 on the outside of the blade and the thickness dimension of the sheet-like workpiece W. value. Thus, when the sheet-like workpiece W is mounted on the upper side of the blade outer elastic member 6 by the cutting die body 2, the end face of the sheet-like workpiece W can be abutted against the pin portion of the correspondingly disposed pin 10. 12 side. Therefore, the movement of the sheet-like workpiece W mounted on the die body 2 in the direction in which the pins 10 are arranged is suppressed.

In this state, each pin 10 is capable of sandwiching the edge of the sheet-like workpiece W with the blade outer elastic member 6 through the step portion 14 between the pin portion 12 and the pin head portion 13. This can prevent the edge of the sheet-like workpiece W mounted on the die body 2 from floating.

The reason why the pin head portion 13 is formed in the shape of a conical ladder is that when the cover body 3 is placed on the upper side of the sheet-like workpiece W mounted on the die body 2 through the inclined surface on the outer periphery of the pin head portion 13, it is easy The correspondingly disposed pins 10 are inserted into the respective pin insertion holes 11 of the cover 3.

The size of the pin 10 protruding from the surface of the base plate 4 and the thickness of the cover body 3 are set so that the cover body 3 is lowered to each of the cutting blades 5 in order to cut the sheet-shaped workpiece W by each cutting blade 5. When the blade tip 5a penetrates the position of the lower surface of the cover 3, the top of the pin 10 does not protrude upward from the cover 3.

According to the configuration in which the die body 2 is provided with the pin 10 and the cover body 3 is provided with the pin insertion hole 11, the horizontal direction of the cover body 3 with respect to the die body 2 can be restricted when the pin 10 is inserted into the pin insertion hole 11. Relative position. This can eliminate the possibility that the position of the sheet-like workpiece W or the workpiece cutting piece X is shifted toward the horizontal direction with the cover 3 in contact with the upper surface side thereof.

Furthermore, among the blade inner elastic members 7 disposed inside the respective cutters 5, the fluororesin sheet 9 provided on the upper surface of the blade inner elastic members 7, and the base plate 4 become the inside of each blade 5. A suction hole 15 penetrating in the up-down direction is provided at the portion. Thereby, in the cutting die body 2, the unconnected end connected to the lower end side of the suction hole 15 is used. The suction device shown in the figure sucks through the suction hole 15 to suck and hold the sheet-shaped workpiece W that is die-cut by the cutter 5 to the workpiece cutting piece X, and to hold it on the upper side of the blade-side elastic member 7. The suction hole 15 is provided on the blade outer elastic member 6 and the blade outer elastic member 6 even if it is located on the outer side of the cutter 5 and at the position where the remaining sheet Y is arranged. The fluororesin sheet 9 on the upper surface, and the base plate 4. Accordingly, in the cutting die body 2, even the workpiece cutting piece X and the remaining piece Y after being cut off can be sucked and held on the upper side of the blade outer elastic member 6 by suction through the suction hole 15.

When using the cutting device 1 of the present invention having the above configuration, the cover body 3 is arranged at a position far from the cutting die body 2 or the cover body 3 is moved so as not to be caught in the cutting die body 2. In a state of the upper position, the sheet-like workpiece W is mounted on the upper surface of the blade outer elastic member 6. At this time, the corresponding end surface of the sheet-like workpiece W is placed against the pin shaft portion 12 of each pin 10.

Next, as shown in FIG. 1A, a cover body 3 is mounted on the upper side of the sheet-like workpiece W set on the die body 2. As a result, the sheet-like workpiece W is mounted on the cutting device 1 of the present invention.

Next, the die cutting device 1 of the present invention is relatively moved in the direction of the arrow D shown in FIG. 2 with respect to the pressing roller of a roller press (not shown), while the pressing roller 1 is moved from the two vertical directions by the pressing roller. Press the die body 2 and the cover 3 side or side.

Thereby, as the area subjected to the pressing load by the pressing roller moves in a direction opposite to the direction of the arrow D in FIG. As shown in FIG. 1B, the area subjected to the pressing load can relatively lower the cover body 3 to the cutting die body 2 down to a position where the tip 5 a of each cutter 5 penetrates the lower surface of the cover body 3. The sheet-like workpiece W pushed down by the cover 3 is cut in order by the cutting edges 5 a of the cutting blades 5 being sequentially deepened. At this time, the sheet-shaped workpiece W located on the upper surface of the cutter 5 is pushed downward and enters the cutter 5 as shown in FIG. 3 when it receives the pressing load from the pressing roller. It is inwardly connected to the tip 5a of the cutter 5. The sheet-shaped workpiece W is when the tip 5a of the cutter 5 penetrates, the position where the tip 5a penetrates is restricted by the cutter 5 to the relative displacement with the cutter 5. Therefore, the sheet-like workpiece W can be prevented from being shifted relative to the cutter 5 while being sequentially cut while receiving the pressing load applied by the pressing roller. In this way, by cutting the sheet-like workpieces W by the cutters 5, it is possible to form the workpiece-cutting pieces X after die-cutting inside the respective cutters 5. The workpiece cutting piece X is received by the inside of each cutter 5 by an elastic member 7 inside the blade.

At this time, from the sheet-like workpiece W, a remaining sheet Y is simultaneously formed on the outside of each cutter 5. The remaining sheet Y is cut into a size that can be easily handled by the remaining sheet cutting blade 8.

In the die cutting device 1 of the present invention, in this state, the suction holes 15 are sucked by the suction device, and the workpiece cutting pieces X are respectively adsorbed on the upper surface of the elastic member 7 inside the blade, and the remaining pieces are made. Y is adsorbed on the upper surface of the elastic member 6 on the outside of the blade.

In addition, in FIG. 1B, although the cover body 3 is shown pushed down for the sake of convenience of illustration, in fact, the cover body 3 is affected by the pressing load applied by the pressing roller. Area is It moves in the direction opposite to the direction of arrow D (refer to FIG. 2) in sequence. Therefore, the cover 3 is surely pressed to a position where the tip 5a of the cutter 5 penetrates into the cover 3, and also faces the direction of the arrow D. The opposite direction moves in order. Therefore, since the cutting of the sheet-shaped workpiece W by each cutter 5 is actually sequentially performed in a direction opposite to the direction of the arrow D, the adsorption and alignment of the workpiece cutting piece X by the aforementioned suction hole 15 is performed. The adsorption of the remaining sheet Y is performed sequentially at the time point when the workpiece cutting sheet X and the remaining sheet Y are formed.

After that, when the pressing of the cutting die device 1 of the present invention by the pressing roller is completed, the cover 3 is restored to the initial shape by being compressed from the blade outer elastic member 6 in a vertical direction, as in the first embodiment. As shown in FIG. 1C, push up to the initial position above the die body 2.

At this time, since the height dimension of the elastic member 7 inside the blade is set to be lower than the protruding height of each cutting blade 5 from the surface of the base plate 4 to the cutting edge 5a, as described above, the sheet-like workpiece W is Before cutting, the sheet-like workpiece W is pressed into the inside of the cutter 5, thereby preventing positional deviation of the sheet-like workpiece W during cutting. After the sheet-like workpiece W is cut, the workpiece cutting piece X is held inside the cutter 5. On the other hand, the remaining sheet Y moves to a position higher than the tip 5 a of each cutter 5 as the blade outer elastic member 6 is restored to the initial shape.

At this time, as long as the workpiece cutting piece X is attracted to the upper surface of the blade-side elastic member 7 by the suction of the suction hole 15, the cover 3 is upwardly moved by the blade-outside elastic member 6. When pushing, it is possible to more reliably prevent the work cutting piece X from being attracted by static electricity or vacuum. Suction and follow the movement of the cover 3.

Then, the work cutting piece X is in a state where the cover body 3 is placed away from the upper part of the cutting die body 2 or the cover body 3 is moved to a position where it cannot be caught on the upper part of the cutting die body 2 by A picking device (not shown) picks up from the inside of each cutter 5. The remaining sheet Y is removed from the upper side of the blade outer elastic member 6 using another picking device (not shown).

At this time, as long as the remaining sheet Y is removed earlier than the pick-up of the workpiece cutting sheet X, the remaining sheet Y will not interfere with the remaining sheet Y even if the position on the blade outer elastic member 6 has shifted from the remaining sheet Y. Pick-up of the work piece X can be performed.

Thus, according to the cutting device 1 of the present invention, since the position of the upper surface of the elastic member 7 on the inner side of the blade provided inside the cutter 5 is lower than the height of the tip 5a of the cutter 5, it is as shown in FIG. It is shown that the sheet-like workpiece W can enter the inside of the cutter 5 in a concave shape, and can be received by the elastic member 7 inside the blade. In this state, since the sheet-like workpiece W is in contact with the corresponding cutter 5, it is possible to prevent the position of the sheet-like workpiece W from being shifted relative to the corresponding cutter 5 when the sheet-like workpiece W is cut.

Further, in the cutting die device 1 of the present invention, the workpiece cutting piece X formed by cutting from the sheet-like workpiece W is held inside the cutter 5. In this state, the outer peripheral end of the workpiece cutting piece X will contact The corresponding cutters 5 are connected. Therefore, since the position of the work cutting piece X is restricted by the cutter 5, the cutting device 1 of the present invention can prevent the formed work cutting piece X from being deviated from the position of the corresponding cutting blade 5. shift.

The cutting device 1 of the present invention has a structure in which the cutting device 1 of the present invention is inverted upside down. As a second embodiment, it is pressed by a pressing roller. The same can be achieved in the same manner as in the previous embodiment. The sheet-like workpiece W is prevented from being displaced, and is cut and die-cut while being cut.

That is, in this embodiment, the die cutting device 1 of the present invention shown in Figs. 1A, 1B, and 1C is completely reversed, and the pressing roller (not shown) of the roller press is used. The cutter body 2 and the lid body 3 are pressed from both sides or one side in the up-down direction, and as described above, the area that receives the pressing load applied by the pressing roller is sequentially moved while the cutter is moved. 5 Dive into the sheet-like workpiece W and cut.

At this time, the sheet-like workpiece W located below the cutting blade 5 that is downward is pushed through the cover 3 by the movement of the area that receives the pressing load applied by the pressing roller, and is thus in the position. The sheet-like workpieces W inside the cutter 5 are sequentially cut in a state where they are pushed into the cutter 5.

In this case, when the sheet-like workpiece W receives a pressing load from the pressing roller from below, it enters the inside of the cutter 5 and easily contacts the tip 5 a of the cutter 5.

Thereby, the sheet-like workpiece W is cut without being shifted in position during the cutting by the cutter 5 and die cutting. At the same time, the remaining sheet Y is cut by the remaining sheet cutting blade 8.

In this way, when the cutting die body 2 ends the pressing of the cutting die device 1 of the present invention with respect to the sheet-like workpiece W in an upper position, the cutting die device 1 of the present invention is reversed again, and as shown in FIG. 1A and FIG. 1B picture, As shown in FIG. 1C, the sheet-like member W and the cover 3 are arranged above the die body 2.

Subsequent operations are the same as the first embodiment shown in FIGS. 1A to 5.

In addition, the present invention is not limited to the foregoing embodiments, as long as the height dimension of the elastic member 7 inside the blade can be set to be smaller than the protruding height of the cutter 5 from the surface of the base plate 4 to the tip 5a, Moreover, the height of the blade-side elastic member 7 can also be appropriately changed by a step difference between the surface of the blade-side elastic member 7 and the blade tip 5a of the cutter 5 to enter the sheet-shaped workpiece W inside the cutter 5.

The shape, number, and arrangement of the cutters 5 included in the cutting die body 2 may be set to any shape, number, and arrangement other than the illustration. In addition, the shape, arrangement, and number of the remaining sheet cutting blades 8 can be freely set according to the shape, number, and arrangement of the cutting blades 5.

The pin 10 provided in the cutter body 2 may be formed in a cylindrical shape from the upper end to the lower end, instead of a pin head 13 provided with a conical ladder shape on the upper side of the pin portion 12 shown in FIG. 4. Make up. Even with this configuration, the following effects can be obtained: the effect of preventing the relative displacement of the cover body 3 with respect to the cutting die body 2 in the horizontal direction; and the effect of abutting against the sheet-like workpiece W mounted on the cutting die body 2 The effect of preventing the positional deviation of the sheet-like workpiece W by the end surface.

In addition, the pin 10 provided in the cutting die main body 2 may be disposed so as to prevent the displacement of the cutting die main body 2 and the cover 3 only for the purpose of preventing the offset between the cutting die main body 2 and the cover 3. Sheet-like work on the mold body 2 The piece W interferes at an arbitrary position.

In addition, the die cutting device 1 of the present invention can also use a pressing mechanism in the form of pressing the base plate 4 and the cover 3 of the die main body 2 uniformly over the entire surface as a die for cutting from a sheet-like workpiece W. Instead of a roller press, a pressing mechanism in which the pressing load of the work piece X acts. In this case, the number of pins 10 provided in the cutting die body 2 can also be reduced.

It is needless to say that various changes can be made within a range not departing from the gist of the present invention.
